1313 ETN9/C3 Bearing Product Overview & Core Advantages
The 1313 ETN9/C3 is a double row angular contact ball bearing engineered for demanding applications requiring high load capacity and robust performance. This precision bearing is designed to accommodate significant combined loads, including radial and axial loads in both directions, within a compact bearing dimension profile. Its open design, optimized internal geometry, and C3 radial internal clearance make it an ideal choice for arrangements where thermal expansion and high operational stability are critical. Manufactured from high-grade chrome steel, it delivers exceptional durability and reliability in industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating the basic size and type. |
| E | Optimized internal design, typically providing high load carrying capacity. |
| TN9 | Nylon (polyamide) cage, pressed window type. This design is lightweight, promotes lower friction, and is suitable for high-speed operation. |
| C3 | Radial internal clearance greater than Normal (CN). This is selected for applications with expected thermal expansion, interference fits, or heavy loads to prevent premature failure. |
1313 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial combined radial and axial loads from both directions simultaneously, making it more compact than two single-row bearings.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces and inertial mass, which is crucial for maintaining stability and extending service life at the limiting speed of 6,000 rpm.
- Precision and Stability: Manufactured from high-carbon chrome steel for both rings and balls, ensuring consistent performance, high wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
- Pre-Lubricated for Immediate Use: The bearing comes pre-lubricated, ensuring immediate operational readiness and initial protection against wear.
1313 ETN9/C3 Bearing Typical Application Areas
The 1313 ETN9/C3 is suited for a wide range of industrial machinery where high load capacity and operational reliability are paramount. Key applications include:
- Industrial Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable shaft support
